Stock price when the opinion was issued
Enbridge wants to buy ENF to simplify their corporate structure. In the States, Enbridge offered a small premium, while in Canada, they offered a premium. He suspects the directors of ENF-T are waiting for a higher premium (or that's what he would do). Pays a higher yield than Enbridge Inc. but lacks the dividend growth potential.
For an income investor he continues to hold, but on the equity side the trend has been breaking down and he will be selling soon. Not a great stock for growth, but if you like the 4% dividend you should continue to hold.
